Fallback definitions
As this package provides many SEO related fields and mechanisms it can be a lot of work for editors to fill everything the way it should be.
Therefore several default fallback chains are provided for the output. Those are described in the following sections.
Our goal is to make it easy for integrators to extend these chains. You can find them in the individual Fusion objects. And feel free to created issues on Github if you think that something could be improved!
